Title: Pll circuit
Inventor: OISHI SHOJI
IPC: H03L7/08
Filed: 1995-03-08
Abstract: PURPOSE: To make characteristics stable even if a power source or temperature varies by using the output signal of a 2nd PLL circuit, which includes the difference component between the frequency of a 2nd external signal and the internal oscillation frequency, as a pulse control signal. CONSTITUTION: A 1st PLL circuit 100 is constituted as a PLL circuit which locks the phase for a 1st external signal S1 and the 2nd PLL circuit 200 supplies a pulse control signal so as to control the pulse width of reference pulses of the circuit 100. A reference pulse generation part PA generates the reference pulses having a period a half of a signal S1 , and a phase comparison part PB compares the output of a voltage-controlled oscillator 16 with the reference pulses and outputs a comparison signal. A low-pass filter 15 passes the difference component between the output of the oscillator 16 and the frequency of the reference pulses among frequency components of the comparison signal supplied from the comparison part PB.  Here, the output signal of the circuit 200 which includes the difference component between the frequency of the 2nd external signal S2 and the internal oscillation frequency is used as a pulse width control signal to facilitate the setting of a delay quantity.

Title: Semiconductor laser device
Inventor: MURAKAMI TAKASHI
IPC: H01S5/16
Filed: 1984-03-12
Abstract: PURPOSE:To render thermal destruction difficult to occur at an end face and thereby to realize high output by a method wherein the liquid phase crystal growth method is employed to realize an activation layer thinner in the vicinity of the end face and provided with a larger band gap. CONSTITUTION:On a substrate 1a, a lower clad layer 2a, activation layer 3a, uppsr clad layer 4a, contact layer 5 are grown by the liquid phase growth method, in said order. In the vicinity of the light-emitting end face, the band gap of the activation layer 3a grown on a ridge 8 is larger than that of an activation layer 3al located within the chip. It hollows that the end face is transparent to the light generated within the chip and does not absorb the light. It is difficult for the end surface to be damaged due to high temperatures attributable to absorbed light. Near the end face, where the activation layer 3a is thin, light oozes out to arrive at the clad layers 2a, 4a, lowering optically energy density. With the window and the light-emitting portion growing simultaneously, they are less prone to have faults and are easier to manufacture, leading to a high energy laser.

Filed: 1984-03-16
Abstract: PURPOSE:To obtain a high active catalyst by regulating the softening point of liquefied residue supplying to a metallic bath gasification furnace. CONSTITUTION:In the method wherein coal liquefaction residue is gasified by using a metallic bath gasification furnace and simultaneously produced solid finely powdered is recovered as a catalyst for coal liquefaction, the softening point of the feeding liquefaction residue is regulated to >=120 deg.C preferably >=150 deg.C. As a general method regulating the softening point of said liquefaction residue as raw materials, in case wherein the softening point of the raw material residue is <=120 deg.C, the remaining oil is recovered with vacuum distillation and steam distillation or the like or the softening point of distillation residue is elevated with a thermal decomposition apparatus such as delayed coking. Namely, since the higher said softening point of liquefaction residue as raw materials is, the more specific surface area and micropores of said produced solid finely powdered are increased, a catalyst for liquefaction having high catalytic activity is obtained and the yield of liquid is increased. Further, when the softening point is >=150 deg.C, a nozzle of lance is not clogged and stable operation is made possible.

When this pilot arc transfers to the plasma arc 2 generated between the electrode 1a and the work 5, the output current  from an electric power source 4 increases and therefore it is detected with a current detector 7. After the time T3 from this detection, the supply of the 2nd  working gas G2 consisting of dissimilar gases of Ar+H2, Ar+N2 or N2 is  started and is mixed with the gas G1. After the supply of the gas G2, the work  5 and the torch 1 are moved relatively.

Filed: 1989-03-01
Abstract: PURPOSE:To make a switch useful in various ways and durable with cost lowered as well as to contrive to enhance productivity by permitting a section formed into a tray shape of a thermal reaction sheet to be turned over because of its snap action so that the sheet lose contact with a fixed contact point, and permitting the sheet to be returned back to the direction of an original curvature with a snap when it becomes less than a specified temperature. CONSTITUTION:A thermal reaction sheet 2 is formed with a section 2B drawn into a shallow tray shape roughly at its center position, and when the temperature of the thermal reaction sheet 2 comes up to a specified one, the sheet is turned over because of its snap action so that current to a motor permitting a movable contact point 2A to lose contact with a fixed contact point 7, is interrupted. After the sheet has been cooled as it is, the thermal reaction sheet 2 is returned back again with a snap. By this constitution, productivity is improved, and thermal reaction switch can thereby be obtained, which widens the range of current to be appllied while being made durable with cost lowered.
